>>>I haven't found a practical limit to the path setting. From what I've seen it looks like you're using relative paths. Naturally, if you move the application to a folder where the relative paths are no long valid, VFP isn't going to be able to resolve them. Use full paths if necessary. Note: The only time I've run into this problem is when the source isn't on the current setting.

Yes, since it works from its own directory. Anyway, I gave up and I'm testing it from its own directory now. Unfortunately, the code is overcomplicated and very deep, so I clicked run to cursor at the wrong place now. I'll try again.
